Need help with A and B

a. 0.29

b. 0.24

Step-by-step explanation:

a.

visualize in 100% block instead of decimal, so multiply the decimals by 100;

0.01* 100 = 1

0.3 * 100 = 30

now subtract "0.01 from 0.3" OR subtract 1 from 30 which is 30-1=29;

now convert back to decimal by diving by 100 (29/100) or moving the decimal two places to the left, you get 0.29

b.

eighth hundredths is or 0.18

and three tenths is or 0.3

the decimal is halfway between 0.18 and 0.3,

you can subtract and then divide by two and add it to 0.18,

like this (0.3 - 0.18) = 0.12, now divide by 2

0.12/2 = 0.6, now add it to 0.18 to find the halfway decimal between 0.18 and 0.3.

So 0.18 + 0.6 = 0.24
