This problem is about whole numbers and decimal numbers, specifically, we need to use tens, tenths, and hundredths.
Notice that the number 10.74 is composed of 1 ten, 0 units, 7 tenths and 4 hundredths, that's one way you can make 10.74, that is
1*10 + 7*0.10 + 4*0.01 = 10 + 0.70 + 0.04 = 10.74
Another way to make 10.74 would be 10 units, 7 tenths and 4 hundredths:
10*1 + 7*0.10 + 4*0.01 = 10 + 0.70 + 0.04 = 10.74
There you have it, two ways to make 10.74.
