Answer:
1.) 25%
2.) 20%
3.) See Step-By-Step Explanation #3.
4.) a.) Kasuko b.) See Step-By-Step Explanation #4b
Explanation:
1.) 12 / 48 = 1 / 4 = x / 100 so x = 25 meaning that Rita got a 25% discount.
2.) 25 / 125 = 1 / 5 = x / 100 so x = 20 meaning that Masako got a 20% discount.
3.) First, you take the discount that you got to find the fraction of the original price discounted and convert it to a fraction with a denominator of 100, making "x" the percentage discounted on the purchase.
4.)
a.) 25/110 > 25/125
b.) If the numerator of 2 fractions are equal, the larger denominator is smaller.
