Answer is 0.05. 2 people told me they were going to give me brainlest but didn’t so please give me brainlest
Answer:
4%
Step-by-step explanation:
(13.52-13)/13=0.52/13=0.04
reduce 12/20 to 3/5
multiply both top numbers and then both bottom numbers
8 x 3 = 24
19 x 5 = 95
so answer is 24/95
Let us calculate the teacher's initial speed. It can be calculated as thus:
She does 5 papers in 30 minutes. Thus means her speed is 6 minutes per paper (Because
minutes per paper).
Now, if the teacher has to complete the remaining 30 papers in the remaining 150 minutes (2 hours 30 minutes=120+30=150 minutes), she will have to go through one paper in
minutes. Thus, her speed now will have to be 5 minutes per paper.
Now, we know that 1.2 times 5=6. Therefore, it will not be wrong to say that '' she has to be 1.2 times faster instead of 20% faster" because both mean the same.
