There are 420 girls and boys at a concert The ratio of girls to boys at the concert is 3 to 7 How many girls are at the concert?
3+7=10 (3 and 7 are both ratio numbers) 420/10=42 (10 is the sum of both ratio) 3x42=126 girls (3 is ratio of girls) 7x42=294 boys (7 is ratio of boys)
What ratio is equivalent 16 to 6?
Ah, what a happy little question! To find the equivalent ratio to 16:6, we can simplify it by dividing both numbers by their greatest common factor, which is 2. So, 16 divided by 2 is 8, and 6 divided by 2 is 3. Therefore, the equivalent ratio is 8:3. Remember, there are no mistakes in ratios, just happy little simplifications!
What is the ratio of 72 to 45?
72 is 8/5 of 42, or 160% of 45
What is the simplest form 95 to 160 ratio?
95 : 160 = 19 : 32
What will be the first term and the common ratio of geometric progression whose 6th and 9th terms are 160 and 1280 respectively?
To find the first term and common ratio of a geometric progression, we can use the formula for the nth term of a geometric sequence: (a_n = a_1 \times r^{(n-1)}). Given that the 6th term is 160 and the 9th term is 1280, we can set up two equations using these values. From the 6th term, we get (a_1 \times r^5 = 160), and from the 9th term, we get (a_1 \times r^8 = 1280). By dividing the two equations, we can eliminate (a_1) and solve for the common ratio (r).
