Divide 33 photis into two groups so the ratio is 4 to 7

In this question, most of the vital information's are already provided. based on these information's, the required answer can be easily deduced. It is already given that there are 33 photis in total. The ratio is 4:7.

Let us assume the common ration = x

Then

4x + 7x = 33

11x = 33

x = 33/11

= 3

So the photis are divided into

4 * 3:7 * 3

12:21

So the 33 photis are divided in the ratio of 12:21

A way you can do tis is add the ratio together and then divide 33 by the added number. 4+7=11 33/11 = 3 Now multiple the ratio by 3 to get your two groups

4x3=12 7x3=21 12+21=33 12 and 21 are your two groups for the ratio 4:7
