It is 150 percent
Step-by-step explanation:
You can find this value by dividing the numerator by the denominator, summing this value to the integer part and multiplying the result by 100%, so:
1 1/2 in percent = (1 + 1/2) × 100% =
(1 + 0.5) × 100% = 1.5 × 100% = 150%
Hope this helps! Sorry if I'm wrong.
26x3=78
78-x=72
x=6
She needs to buy at least 6 more to have enough for 26 students
So let's find the unit rate of these.
