Answer:

Henry is 5kg short of cement.

Step-by-step explanation:

4:3:1

Cement : Sand : Gravel

We can also write the ratio as:

4 x Gravel : 3 x Gravel : 1 x Gravel

Therfore a logical "x" would be the amount of gravel.

If we substitute gravel with x and put it in an equation we get:

4x+3x+x=120

8x=120

x=120/8

x=15

This way we can check if each value is correct.

x = Weight of Gravel = 15kg Correct

3x = Weight of Sand = 45kg Correct

4x = Weight of cement = 60kg WRONG!

The actually weight of cement is 55kg.

Therefore Cement is 5kg short.
