The benchmarks are 1 1/2 0
0:10 + 2:00 + 0:25 = 2:35
yes 2/4 is because it is equivalent to 1/2 which is a benchmark fraction.
A decimal benchmark example would be 43 divided by 2. a decimal benchmark would be 42 divided by 2 because everyone knows that all even numbers are divisible by 2
Benchmark Decimals are fractions (decimals) like 0 1/2 1/4 .25 .50 .75 like that!
1/4 is exactly half way between 0 and 1/2.

-2x^2 + 17x - 35 = 0 = (-2x + 7)(x - 5) x =7/2 or 5

3:00 - 0:35 = 2:25
lesson 2 on problem solving. what are common methods for establishing a benchmark?
3/7 is closest to the benchmark fraction (1/2), so: 3 1/2
1/2 of a mile
(60 + 10) ÷ 2 = 35
