Kylee's 3rd Growing Post

Race Strategies

The whole matters
Measurement/Fractions are operators
ugly fractions/friendly fractions
Propotional Reasoning
Partial Products

Ok so first of all I have to figure out how far Mark would have ran if he ran 7/8 of the course. And how far Racheal wold have ran if she ran 11/12 of the course.

The whole matters-in the first picture both Racheal and Mark both ran a whole of 26 miles. Each ran 5/8 and 7/12.

Measurment/Fractions are operators-in the second picture you have to add 1/8 five times, so that it equals 5/8. Then 4/7 of the way. 1/2 of the course, 1/2 of 26, 7/12=1/12,1/2x26.
ugly fractions/friendly fractions-5/8-> 1/8+1/8+1/8+1/8+1/8/ 1/8x5.
5/8 of 32=4+4+4+4+4=20 5/8=20

Proportional Reasoning- Ratio Table. In question #3 we used a ratio table to find out how many miles they ran this year.
flags 1/12, miles 2 1/6, 7/12=15 1/6.
water/miles 16 1/4
Partial Products-5/8=1/2+1/8 4/8+1/8
Partial Distributive
Products Property
5/8 4/8+1/8=5/8
7/12 1/2+1/12=13m.
