Question

how you can use base-ten blocks to find 1.54+2.37?

Answer 1

We can use 100s for ones place, 10s for tenth place and 1s for hundredth place.

Addition of 4 and 7 in the hundredth places will give 11.

Replace 10 blocks with 1 tens block.

Add this 1 to 5 and 3 which are in tens place. This will be 1+5+3 = 9.

Addition of 1 and 2 in ones places 3.

Hence, the answer is 3.91.
