think of this...what is 3/4 of 100...how do you solve this? what is the answer? lets do a simple one

What is 1/2 of 100? let's multiply 1/2 and 100 so 1/2 x 100 which is 1/2 x 100/1...correct??

we know the answer is 50, right? we get this by multiplying 1 times 100...the numerator and 2 times 1,

the denominator...correct? now we have 100/2...correct? do you see? just complete the division operation,

which is 100 ÷ 2 = 50 correct?

now you do your problem...3/4 x √45 which is the same as 3/4 x √45/1...

now you have 3 x √45/4 x 1 so simplify 3√45/4...complete the operation...try more problems

the more you work the easier they will become

The square root of 45 should be simplified to 3v5 in the final answer.
