jane runs 12 miles a day.
how many miles does she run in 76 days?
12 * 80 = 960
12 * 70 = 840
75 is close to 76 and halfway between 70 and 80, therefore your answer will be halfway between 840 and 960.
960 - 840 = 120.
half of 120 = 60
add 60 to 840 to get 900
subtract 60 from 960 to get 900.
that would make the estimate about 900.
another way to estimate would be 10 * 75 + 2 * 75 = 750 + 150 = 900.

12*76 = 912
Miles = approximately 911.
Call 911.

You can get a good estimate by multiplying by 75 instead of 76.
Multiplying by 75 is not too hard, because it is 3/4 of 100. So
So 900 is a good estimate for 12 times 76.
