Answer:
3) 8
4) 5.25 cups
Step-by-step explanation:
3) cross multiply:
36 × 10 = 360
45 × x = 45x
equate them both:
360 = 45x
divide both sides by 45
360 ÷ 45 = 8
x = 8
4) 8 people : 3 cups of flour
14 people : how many cups?
14 ÷ 8 = 1.75
to get from 8 people to 14 people we multiply by 1.75, so do the same thing to the 3 cups:
3 × 1.75 = 5.25 cups
I'd say (a) = 52.5 minutes or 52 minutes and 30 second
(b) = 45 minutes
Answers A and C and correct for this equation.
Answer:
No sé pude simplificar ya que ambos no tiene divisores en común. Pero si lo deseas dividir daría como resultado: 2 ÷ 3 = 0.6666666667
