Fruit: yoghurt: total
2: 3: 2 + 3
2: 3: 5
5 parts = 185
1 part = 185 ÷ 5 = 37
3 parts = 37 x 3 = 111g
The weight of the yoghurt is 111g
To find the number of tails, subtract 225 from 500, yielding 275. So, we establish a ratio of 225 to 500, which needs to be simplified. Dividing both by 25 gives us 9 and 20 respectively. Therefore, the simplified ratio is 9:20.
I think the rule to follow is to multiply the first number by the second and then add the first number. For example:
in the case of the first one, 1 x 4 = 4, then 4 + 1 = 5
for the second one, 2 x 5 = 10, and then 10 + 2 = 12...
So for 8+11:
simply multiply 8 x 11 = 88, and then add 88 + 8 = 96
