Answer:
The answer is 700 to the nearest hundred
Step-by-step explanation:
7+9×11
7+99
=106.......By
23% can be written as 0.23.
Multiply any number by 0.23 to get 23% of it.
For Q1, we can start out by turning it into a plain fraction. 16*2=32, and 32+1=33, so 16+1/2=33/2. Similarly, for 2 3/4, 2*4=8 and 8+3=11, so 2 3/4=11/4 as the size of each piece of wood. To divide them, we have the numbers 33/2 and 11/4. We first find the reciprocal of the size of a piece (switch the numerator and denominator) and then multiply the 2 fractions - 33/2*4/11=132/22=6 pieces. Using that, I challenge you to do Q2 on your own!
He bikes 15 miles which is 10 times more than he swims. He runs 9 miles which is half of what he bikes 15/2=7.5. Plus the addition 1.5 miles which is 9. He swims .10 of what he bikes which is 15x.10 which is 1.5 . So he swims 1.5 miles.
Bikes = 15 miles
Run= 9 miles
Swim= 1.5 miles
Add all of them and you get 25.5 which the total amount of miles for his training that day.
