Answer all questions also fill in the blanks.

6. 2.40

7. 0.63

8. 4.36

9. 6.19

Step-by-step explanation:

For numbers 6 and 7:

The whole block represents 100 hundredths. If the entire block is filled, then that is equivalent to 1. (think of it as pennies. one hundred pennies is equal to one dollar). The columns represent tenths, and the individual squares represent hundredths as well.

Two whole blocks are filled in problem 6, plus 4 columns in the third block. So that's 2 and 4 tenths.

For 7, only part of one is filled. Count the number of columns that are filled and then count the individual colored squares in the last column This will give you 6 full columns and 3 filled squares. 6 tenths and 3 hundredths. 0.63

For 8 and 9:

The word and is where the decimal goes in the standard form of the numbers.

Four and thirty-six hundredths = 4.36

Six and nineteen hundredths = 6.19
