2 fifths of a number is 14. what is the number?

Answers

Answer 1
Answer: In math

"of" means times (x)
"is" means equals (=)
"a number" is your unknown which you can call anything but we'll call x

2/5 of a number is 14

Translation...

2/5 * x = 14

Divide each side by 2/5 to isolate x.  To divide a fraction, multiply the reciprocal of the divisor (flip the numerator and denominator).

x = 14 * 5/2
x = 70/2
x = 35

2/5 of 35 is 14.

In a group of 120 seventh graders. 30% have completed their science project. How many students have completed their science project.

Answers

Answer: 36

Step-by-step explanation:

120 students is the same as 100%, so you would divide 120 by 100 and your quotient would be 1.2 Then you multiply 30 by 1.2, since you would multiply 100 by 1.2 to get 120. 30×1.2=36. So 36 seventh graders have completed their science project.
