Answer: 4:20
Step-by-step explanation:
60 lbs can be divided into three groups, in this case the bags of sand, so 60 divided by 3 is 20.
Now you have the 8 lbs left. It gets divided into two groups/bags so you would do 8 divided by 2 is 4.
Then for your ratio it is cement to sand which is 4:20. You can write the ratio however way you want or what is required by the question.(fraction bar, ‘to’, or colon ‘:’ )
