    For now, assume 4/5 and 45/100 are equal fractions

    4/5 = 45/100

    4*100 = 5*45 ... cross multiply

    400 = 180

    Since the left side (400) is larger than the right side (180), this means that the original left side (4/5) is larger than the original right side (45/100)

    We can go back to the steps above and replace every equal sign with a "greater than sign" like so

    4/5 > 45/100

    4*100 > 5*45 ... cross multiply

    400 > 180

    the third inequality is true, which confirms the first inequality must also be true

    Further confirmation can be found through using a calculator to convert to decimal form

    4/5 = 0.80

    45/100 = 0.45

    We see that 0.80 is larger than 0.45, so 4/5 is larger than 45/100.

    4/5 because you have to multiply the denominator by 20 and the numerator by 20 so then you will get your answer 80/100
