Upper primary school mathematics question UPQ347

Sarin and Hairu saved some money in their coin bank. 2/5 of Sarin’s savings was equal to 1/3 of Hairu’s savings. What was the ratio of Sarin’s savings to their total savings?

Solution:

2/5 fraction of Sarin’s savings was equal to 1/3 fraction of Hairu’s saving

Draw the fraction models of Sarin’s saving and Hairu’s saving

Equal the 2/5 of Sarin’s saving to 1/3 = 2/6 of Haiu’s saving

Sarin’s saving = 5 units

Total saving = 11 units

The ratio of Sarin’s saving to their total saving = 5 : 11
