What expression is equivalent to 3/4-1/2? i know it equals 1/4 but what is an expression equivalent to 3/4-1/2?

An expression equal to 3/4 - 1/2 would be 6/8 - 2/4. If you want a different equation altogether, -1\4 + 1/2 would work. Any equation that equals 1/4 will work in this situation.

When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. if you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.
