Barbie is thinking of a number. twenty less than on third of the number 72. find barbie's

First find one third of the number 72. We can do this by either dividing 72 by 3, or by multiplying 72 by 1/3. I will divide 72 by 3.

72/3 = 24

We have completed half of the problem; one third of the number 72. Now the number Barbie is thinking of is twenty less than the number we just found, 24.

To solve this problem subtract 20 from one third of the number 72; 24.

24 - 20 = 4

The number that Barbie is thinking of is 4.

so first since the number is 1/3 i would divide by 3 \

72 divided by 3 is 24

24 - 20 is 4

2 over 5

step-by-step explanation:

the 2: 3 ratio is the length of the ac segment to the cb segment total length. this implies that the ratio between segment ac length and segment ab length is 2: 5. point c is 2/5 from a to b, so the required fraction is 2/5.
