How can you use models to multiply fractions?
No, you cannot use models to multiply fractions!!
How do you multiply fractions by itself?
that is called squaring. write the fraction twice and multiply numerators and denominators. 2/3 x 2/3 = 4/9
How do you triple fractions?
Oaky, you can multiply the fractipn by 3 then put a one under the 3 to make it a fraction then multply
Do you cross multiply with fractions?
yes
When multiplying mixed numbers do you have to multiply the whole numbers or just the fractions?
More than that. You need to multiply the whole number, the farctions AND cross multiply the whole numbers and the fractions. Then add together all the answers. Thus, 23/4 * 56/7 = 2*5 + (3/4*6/7) + 2*6/7 + 3/4*5 Actually, it is far simpler to convert the mixed fractions to improper (top heavy) fractions, and then multiply the numerators together to give the numerator of the answer and multiply the denominators together to give the denominators of the answer.
What does it mean to multiply and divide fractions?
multiply and divide fractions!-.-
Do you inverse multiply to divide fractions?
To divide fractions, you multiply by the reciprocal. For example, 3/4 (divided by) 3/4 would be converted to 3/4 (divided by) 4/3, you just flip the second fraction and multiply as you normally would if you were multiplying them.
How you multiply fractions?
To multiply fractions, multiply the numerators by the numerators, and the denominators by the denominators, and then (if possible) simplify the resulting fraction. For example, 2/3 x 4/5 = 8/15
How do you convert fractions into grams?
It depends what they are fractions of. For fractions of kilograms, simply multiply by 1000 (move the decimal point 3 places to the right).
How can you use models to multiply fractions?
No, you cannot use models to multiply fractions!!
How is dividing fractions different from multiplying fractions?
(3/4) x (5/9) = (3x5)/(4x9) = 15/36, that is when you multiply fractions, you multiply the numerators and form the numerator of the result and multiply the denominators and form the denominator of the result (3/4) / (5/9) = (3/4) x (9/5) = 27/20, that is when you divide fractions, you first invert the fraction by which you are dividing and then multiply the numerators and form the numerator of the result and multiply the denominators and form the denominator of the result
How do you do fractions of fractions?
Multiply them together. For example one half of three tenths is 1/2 x 3/10 =3/20
How do you get a fraction of another fraction?
To get a fraction of another fraction you have to multiply the fractions. To multiply fractions, just use this simple algorithm: Step 1-Turn all whole numbers and mixed numbers into improper fractions. Step 2-Multiply the numerators of the 2 fractions. The answer to that problem will be the numerator of the answer. Step 3-Multiply the denominators of the 2 fractions. The answer to that problem will be the denominator of the answer. Step 4-Reduce.
How do you find volume with fractions?
You multiply the fractions
How is multiplying fractions different from adding or subtracting fractions?
When multiplying fractions, the fractions do not have to have the same denominator as when adding or subtracting. You just multiply the numerators and multiply the denominators, then reduce if necessary.Example : 3/4 x 5/7 -- multiply 3 times 5 and 4 times 7 = 15/28Example : 2/3 x 6/7 -- multiply 2 times 6 and 3 times 7 = 12/21* In this case, you can divide by 3/3 to reduce the fraction to 4/7
How do you multiply fractions without even fractions?
Just straight across. 1/3 * 1/13 = 1/39 =======and with any multiplication of fractions
Do you multiply the denominator when you multiply fractions?
Yes you do.
