Use the fact that 1 cup equals about 236.59 milliliters.

0.04

Practice makes perfect

We want to express 10 milliliters in cups. 10 mL≈ c We can do this by using the fact that 1 cup equals about 236.59 milliliters. Let's write this relationship as a unit ratio. 236.59 mL/1c To perform the conversion, we need to multiply 10 milliliters by the unit ratio or its reciprocal. Remember, we want to get the capacity in cups, and every unit we do not want has to be divided out.

10 mL≈ 10 mL * 1 c/236.59mL
10 mL≈ 10 mL/1 * 1 c/236.59mL
10 mL≈ 10 mL* 1 c/1* 236.59mL
10 mL≈ 10 mL* 1 c/1* 236.59mL
10 mL≈ 10 * 1 c/1* 236.59
10 mL≈ 10 c/236.59
10 mL≈ 0.042267 ... c
10 mL≈ 0.04 c

We found that 10 milliliters is equal to about 0.04 cup. We can now complete the given statement. 10 mL≈ 0.04 c
