How many points does a student need to score 70% on a 80 point test?

56

Step-by-step explanation:

70÷100×80=56

56

Step-by-step explanation:

Another way to write this question is "What percent of 80 is 70%."

So we would write a percent proportion:

x/80=70/100

To find x, we will do (80*70)/100 which is 5600/100 which is 56.

You could also use benchmark fractions:

10% of 80 is 8

10% * 7 = 70% so 8 * 7 also equals 70%

8 * 7 = 56

Hope this helped, let me know if you have any questions.

the first one, all those points on the line just make a strait line.
