# Apizza was divided into 2 parts in ratio 3: 5. the smaller was then divided in the ratio 2: 3.if the smaller of the two latter pieces weighs 60 grams. what is the weight of the whole pizza

Step-by-step explanation:

Divide 60 by 2

60÷2=30

Multiply the quotient to 3

30 × 3 = 90

So 90g is the weight of the bigger piece

90+60=150g is the weight of the smaller part of the whole pizza

Divide 150 to 3

150÷3=50

Multiply it by 5

50×5=250g is the weight of the bigger part of the whole part

Add all of the weight

250+150+90+60=550g is the weight of the whole pizza

to solve for the time of each printer, divide the given rate from the work done

step-by-step explanation:

q: how did you compute the time of each printer?

given the following:

"you printed your 40-page reaction paper. you observed that printer a in the internet shop stopped printing in two "

from the text, we can know the rate of printer a.

rate = work done divided by the time it took to have the work done.

rate = rate of printer a = time = work done divided by the rate

by using fraction or ratio and proportion, we can solve the following problems:

1. 45 pages = w minute/s

2. 150 pages = y minute/s

let w, y, be real numbers.

to solve for 1, we will equate the given rate with the problem. simply put: = by cross multiplication,

40w = 45 * 2

solving for w,

w = w = = 2.25

the rate for 1 is equals to to solve for 2, = by cross multiplication,

40y = 150 * 2

solving for y,

y = w = = 7.5

the rate for 2 is equals to " printer b can print x pages per minute, how long will it take to print p "

from the text, the rate of printer b is given.

rate of printer b = 1. 30 pages = r minute/s

2. 35 pages = s minute/s

let r, s, be real numbers.

to solve for 1, we will equate the given rate with the problem. simply put: = by cross multiplication,

x * r = 30 * 1

solving for r,

r = r = to solve for 2, = by cross multiplication,

x * s = 35 * 1

solving for s,

s = s = code: 8.3.1.2.1.
