Answer:
105/2 simplified - 52 1/2
Explanation:
I got this answer by turning 70 into a fraction - 70/1 and using cross multiplication.
When you multiply a whole number by a fraction, multiply the whole number by the numerator, then divide that by the denominator.
70 x 3/4 = (70 x 3) /4 = 210/4 = 52.5
