Hello from MrBillDoesMath!
Answer:
example estimates: 1.3, 1.4
Discussion:
According to the question author we need to estimate sum of
9/10 + 7/16
The question is how good an estimate is needed! For example, here's a quick, but hardly accurate, estimate:
9/10 + 7/16 is approx 9/10 + 8/16 = 9/10 + 1/2 = 9/10 + 5/10 = 14/10 = 1.4
Here's a more accurate estimate:
9/10 + 7/16 = (9*8)/80 + (7*5)/ 80 =
(72 + 35)/80 =
107/80 = which is about 1.3
Thank you,
MrB
