What is the GFC of 40 and 60

Mathematics
1 answer:
Svetradugi [14.3K]3 years ago
3 0

Answer:

GCF: 20

Step-by-step explanation:

The thing you want to do is factor both numbers down to their lowest primes.

40:2 * 2 * 2 * 5

60:2 * 2 * 5 * 3

Now underline what is in both sets of primes. I'll bold them. The number that is bolded comes from 2 * 2 * 5 which is 20

The highest common factor is 20

Kerry and three friends went out for dinner. They split a large pizza and each person had a salad and a soda. They want to leave
klio [65]

Answer:

Each person will pay $ 7.20

Step-by-step explanation:

First we find the total bill

Pizza $18.60

Salad $2.50

<u>Soda $2.25</u>

Total  $ 23.35

Sales Tax would be=  8 1/4% of $ 23.35 =$ 1.926= $ 1.93

Tip = 15% of $ 23.35= $ 3.5025

Total Bill paid= $ 23.35 + $ 1.93+ $3.50= $ 28.7825 or $ 28.78

Now dividing the bill among 4 persons = $ 28.78/4= $ 7.196 or $ 7.20

Paying the bill equally is better  and convenient than paying alone as each person gets an equal share of pizza, salad and the soda.
