a student answered 86 problems on a test correctly and recieved a grade 98%.How many problems were on the test, if all the problems were worth the same number of points? (Round to the Nearest whole number.)
X problems.
0,98x = 86.
X =
To determine the number of problems on the test, you can set up a proportion using the given information.
Let's assume the total number of problems on the test is 'x'.
The student correctly answered 86 problems out of 'x'. This can be expressed as:
86/x = 98/100
To solve for 'x', we can cross-multiply the fractions:
98x = 86 * 100
Now, divide both sides of the equation by 98:
x = (86 * 100) / 98
Calculating this, we find:
x ≈ 87.76
Rounding to the nearest whole number, we get:
x ≈ 88
Therefore, there were approximately 88 problems on the test.
