Answer:
15/10
Step-by-step explanation:
Since it is adding you need to get a common denominator(bottom number).
I know that 2 × 5 = 10 so now we multiply 3/5 × 2
we get 6/10
now the problem is 9/10 + 6/10
9 + 6 = 15 and the denominator is 10
15/10
First, subtract to get the difference.
2.85 – 2.78 = 0.07
Next, divide 2.78 by 100
2.78 ÷ 100 = 0.0278
So, 0.0278 is 1%. Divide 0.07 by 0.0278 to get the answer.
0.07 ÷ 0.0278 ≈ 2.518
2.518 ≈2.5
Therefore, the percentage increase is approximately 2.5% (that's the answer).
Hope this helps!
All together it equals (of the number of hours he does in a week)
45 because 6 plus 9 is 15 and 15 multipled by 3 is 45 makes sense becuase .. 6 +3 is 9 and 9 +9 is 18 2 weeks equals 14 days 18 subtracted by 14 equals 2 which 45 subtracted by 2 is 43 and that's the esact number of hours he works 43 in a week.
