first, can you change 1.5 feet into inches?

6. anonymous

no

7. phi

there are 12 inches in 1 foot write the ratio times the number of feet $\frac{12 \ inches}{1 \ foot} \cdot 1.5 \ feet$ now multiply can you do that ?

8. anonymous

what numbers to multiply?

10. phi

1 1/2 (or 1.5) can also be written as 3/2 so you can multiply two fractions $\frac{12}{1} \cdot \frac{3}{2}$

i still can't get the answer

12. phi

are you saying you don't know how to multiply top times top and bottom times bottom in $\frac{12}{1} \cdot \frac{3}{2}$?

13. anonymous

cross multiplication?

14. phi

no, when you multiply two fractions you do top times top bottom times bottom to get a new fraction

15. anonymous

whats the answer the choices are at the top

16. phi

if you would first change 1 1/2 feet into inches, we can get to the problem
