Increase 280 in a ratio 5:2

Answer 1

To increase 280 in a ratio of 5:2, first find the total parts in the ratio:

5 + 2 = 7

Then, divide 280 by the total parts:

280 ÷ 7 = 40

This means each part of the ratio represents 40.

To increase 280 in a ratio of 5:2, multiply 5 parts by 40 and 2 parts by 40:

5 x 40 = 200
2 x 40 = 80

This shows that the ratio of 5:2 is equivalent to 200:80. To increase 280 in this ratio, add 200 and 80:

280 + 200 + 80 = 560

Therefore, to increase 280 in a ratio of 5:2, add 280 to 560. The new amount is 840.
