How many sheets of plywood do you need to cover 3X5 and 2X4 windows?
Divide the area of the windows by the area of the sheets. Note: 3x5 and 2x4 are not areas, they are numbers. And you don't say how big the sheets are, so it is difficult to be helpful.
2x3 plus 3x5- 3x2 equals?
(2x3)+(3x5)-(3x2)= 2x3=6 3x5=15 3x2=6 So..... 6x25-6= 6x25=150 150+6=156
What is the prime factorization of 6 and 15?
6 is 2x3 and 15 is 3x5 just basic facts no exponents

Why don't you change denominators when multiplying fractions?
The way to multiply two fractions is to multiply the numerator by the numerator and the denominator by the denominator, so for example, 2/3 x 4/5 = 2x4/3x5 = 8/15. Or, 1/2 x 2/3 = 1x2/2x3 = 2/6 = 1/3.
What can you multiply by to get 15?
1x15 3x5
