Evaluate a/b for a = 4/5 and b = -9/2
Temka [501]

Answer:

-8/45

Step-by-step explanation:

we can solve a/b by plugging in the given values and we have the new expression:

4/5 / -9/2

to solve, we can use multiply the two fractions together using KCF which stands for: Keep Change Flip. we keep the first fraction as is, change the division sign into a multiplication, and flip the 2nd fraction to its reciprocal (numerator becomes denominator and denominator becomes numerator)

4/5 / -9/2 becomes:

4/5 × 2/-9 < simply multiply the fraction

4 × 2 = 8

5 × -9 = -45

8/-45 is our new fraction. we cannot simplify this any further so this is our answer which can also be written as -8/45

A car travels 150km on 12 L of gasonline. How many liters are there of gasoline needed to travel 500km
coldgirl [10]
150 = 12
150 +150 = 300 which = 24
150 + 150 + 150 = 450 which =36



the remaining 50 is 12 ÷ 3, so 4. 36 + 4 = 40.

therefore, 40 L of gasoline are needed to go 500km
