a student answered 86 problems on a test and got a 98%. How many problems were on the test?
86/x = 98/100
98x = 8600
x =
87
Pls paki answer
To determine how many problems were on the test, we can use a proportion.
Let's denote the number of problems on the test as "x." We can set up a proportion using the student's results:
(86 problems / x) = (98% / 100%)
To solve for x, we can cross-multiply:
86 * 100% = x * 98%
Simplifying, we have:
86 = 0.98x
Dividing both sides by 0.98, we find:
86 / 0.98 = x
x ≈ 87.76
Therefore, there were approximately 87.76 problems on the test. Since the number of problems must be a whole number, we would round up to the nearest whole number. Thus, there were most likely 88 problems on the test.
