You have to answer all of the equations first
-4.8 • 3.2 = -15.36 (negative times a positive is negative)
2 1/4 + (-1 2/5) first find a common denominator, which would be 20
9/4= 45/20
-7/5 = -28/20
since adding a negative is the same as subtracting a positive, you would subtract 45 and 28 which is 17.
17/20 = 1 3/20 (the answer)
turn the fraction into a decimal by dividing the top number by the bottom number, so 17/20 = 0.85
4.92 divided by -3 equals -1.64 (the answer)
-2 3/5 - (-1 2/5)
make them into improper fractions which is -13/5 and -7/5
it stays negative, so the answer is -6/5 or -1.2
so the answer is
-4.8 • 3.2 < 4.2 divided by -3 < -2 3/5 - (-1 2/5) < 2 1/4 + (-1 2/5)
(40 mile) / (80 mile/hour)
= (40 / 80) (mile-hour/mile) = 1/2 hour .
