(6 * 30) + (15 * 42) = 180 + 630 = 810.
6/16 = 3/8
6. (10 x 15) ÷ (10 + 15) = 150 ÷ 25 = 6
6/32, 9/48
3/4 and 6/8
37.5%
(6 * 30) + (15 * 42) = 180 + 630 = 810.
90.
6/16 = 3/8
6/16, or 3/8
It helps you because of the relationship between 3 and 6.6 is twice as large as 3.Therefore if you know the product of 15 and 3 (i.e. 45) then you can calculate the product of 15 and 6 by multiplying this by 2 (i.e. 45 * 2 = 15 * 6 = 90).
6. (10 x 15) ÷ (10 + 15) = 150 ÷ 25 = 6
6 and 9. 6 + 9 = 15 6 * 9 = 54.
Expressed as a decimal, 6/16 = 0.375.
There are 6 of them because 6/16 = 3/8
6 x n = 90 n = 15
six, nine 9 + 6 = 15 (sum) 9 - 6 = 3 (difference) 9 x 6 = 54 (product)
