Question

PLEASE HELP it should be easy for someone but I can’t do it

Answer 1

Total crackers on the plate are 12

Explanation:

Manuel ate crackers =
`(1)/(3)`

His brother ate crackers =
`(1)/(4)`

Crackers left on the plate = 5

We need to find how many crackers were there on the plate.

Let x be the total crackers on the plate

So, we can write the equation

`x-(1)/(3)x-(1)/(4)x=5`

Because 1/3 and 1/4 crackers are eaten and 5 are left so, we subtract 1/3x and 1/4x from x and equal it to 5

`(12x-4x-3x)/(12)=5\\(12x-7x)/(12)=5\\(5x)/(12)=5\\x=(5*12)/(5)\\x=12`

So, we get x = 12

Therefore, total crackers on the plate are 12
