Answer:

Step-by-step explanation:

48 = 16·3

112 = 16·7

80 = 16·5

3, 5, 7 have no common factors. The GCF of {48, 112, 80} is 16.

_____

It can be helpful to recognize 48 = 16·3 and 80 = 16·5. A simple check shows 112 = 16·7, so 16 is the GCF.

You can find GCF(48,112) using Euclid's algorithm:

112 mod 48 = 16

48 mod 16 = 0 ⇒ GCF(48, 112) = 16

and the GCF(16, 80) is ...

80 mod 16 = 0 ⇒ GCF(16, 80) = 16

So, GCF(48, 80, 112) is 16.

Step-by-step explanation:

C= 2000

B = 20/100 x 2000 = 400 + 2000 = 2400

A= 10/100 x 2400 = 240+2400= 2640

2000 + 2400 + 2640 = 7040

11111nata11111 [884]

Whatever% of anything is just (whatever/100) * anything.

so 56% of 75 mates like it, how much is 56% of 75? well is just (56/100) * 75, namely 42.

and 80% of 60 relatives like it as well, how much is 80% of 60? well, is just (80/100) * 60, namely 48.

how many more? well, 48 - 42.

Jake scored 17 out of 25 points on a math quiz. He then scored 16 out of 20 points on a spelling quiz. On which quiz did Jake sc

Nikolay [14]

Answer:

Jake scored more on the spelling quiz. 80% is more than 68% so therefore he scored more on the quiz. To find 80% and 68%, you can use a percent of proportion or divide and multiply by 100.

Step-by-step explanation:

To find the percent of a score, you divide.

17/25 (division) = 0.68

0.68 is a decimal so to make it a percent you multiply by 100 = 68%

Or you can do it with fractions:

17/25 = ?/100: 68

16/20 = 0.8

Again, 0.8 times 100 = 80%

Or you can do it with fractions:

16/20 = ?/100: 80

He scored more on the spelling quiz, I hope this helps (justification on the answer).
