We have an equation: ?/100= 50/125
Cross multiply:
125*?= 50*100
⇒ ?= 50*100/125= 40
40% of 125 is 50~
0 is NOT irrational because it is an integer.
Answer: 2
To factor the expression, you must try to find the greatest common factor of 4 and 6 since you x and y have no common factors. The greatest common factor is 2 for 4 and 6, since when you divide out the 2, you are left with 2 and 3 which cannot be factored anymore.
the pizza is cut into 8 pieces
each piece costs 2.25
so total cost = 2.25 *8 = $18
