HI!!

misty1212 · Answer

volume is the product of all three dimensions
you have to solve $$\frac{5}{7}\times 1\tfrac{1}{2}\times x=\frac{15}{28}$$ for $x$

misty1212 · Answer

first off, do you know how to compute $$\frac{5}{7}\times 1\tfrac{1}{2}$$?

no im not sure

misty1212 · Answer

turn $1\tfrac{1}{2}$ in to an improper fraction, then  multiply straight across

misty1212 · Answer

so i guess the next question is, do you know what $$1\tfrac{1}{2}$$ looks like as  a fraction?
