You may not literally say "multiplied by a half" but multiplying and dividing by fractions are equivalents to doing the other function with an inverse number, most easily in that dividing by 2 is the same as multiplying by (1/2). We don't often multiply and divide by fractions because most of the time we can convert such a problem into a nicer one.
We may use fractions like this, for example, in a test out of 90 marks where one must score 2/3 to pass. This pass mark is obtained by multiplying 90 by (2/3), though this, as said earlier, would usually, even unconsciously with such convenient numbers, be split into "divide by 3, then multiply by 2".
What else can I help you with?
How do use LCM in the real world?
To add fractions.
When multiplying mixed numbers and fractions does changing the order of the factors change the product?
No. The commutative and associative laws are valid for any real numbers.
Why do you use quotients of fractions?
Quotients of fractions are used to simplify the process of dividing quantities, particularly when dealing with ratios or rates. They allow for a clear representation of how one quantity relates to another, making calculations in various contexts, such as in algebra or real-world applications, more manageable. Additionally, understanding quotients of fractions helps in solving problems involving proportions and scaling.
Do real life problems often involve fractions?
Yes, real-life problems frequently involve fractions. They are commonly used in situations such as cooking (measuring ingredients), construction (calculating dimensions), and finance (dividing costs or interest rates). Fractions help in making precise calculations and comparisons, making them essential for everyday tasks and decision-making.
What can you divide into 37?
You can divide any integer or real number into 37, as long as the divisor is not zero. For example, you can divide 74 into 37 to get 2, or 111 into 37 to get approximately 3. The concept of division applies to various contexts, including fractions, percentages, and real-world scenarios like dividing resources.
How is doing operations with rational expressions similar or different from doing equations with fractions and how can they be used in real life?
How is doing operations (adding, subtracting, multiplying, and dividing) with rational expressions similar to or different from doing operations with fractions?If you know how to do arithmetic with rational numbers you will understand the arithmetic with rational functions! Doing operations (adding, subtracting, multiplying, and dividing) is very similar. When you areadding or subtracting they both require a common denominator. When multiplying or dividing it works the same for instance reducing by factoring. Operations on rational expressions is similar to doing operations on fractions. You have to come up with a common denominator in order to add or subtract. To multiply the numerators and denominators separated. In division you flip the second fraction and multiply. The difference is that rational expressions can have variable letters and powers in them.

What can you use gcf for in the real world?
The question presumes that math classes are not part of the real world, which is debatable. The GCF can be used to simplify fractions. Carpenters and chefs use fractions in practical, non-academic settings.
How do GCF and LCM involve with the real world?
Use the GCF to reduce fractions. Use the LCM to add and subtract unlike fractions. Carpenters work with fractions a lot.
Do real life problems often involve fractions?
Yes, real-life problems frequently involve fractions. They are commonly used in situations such as cooking (measuring ingredients), construction (calculating dimensions), and finance (dividing costs or interest rates). Fractions help in making precise calculations and comparisons, making them essential for everyday tasks and decision-making.
What is a real world situation where it is useful to know about factors and multiples?
When adding or subtracting fractions with different denominators and when reducing fractions to their lowest terms.
Is 5i a complex number?
Yes it is. All pure imaginary numbers (such as 5i) as well as all real numbers and any combination of real & imaginary (by adding, subtractin, multiplying, dividing) makes a complex number.
