I disagree. Only 7 is a cube root of 343 (7 x 7 x 7) because -7 is a cube root of -343 (-7 x -7 x -7)

Rates and ratios simalar

Alex777 [14]

Rate is closer to a constant pattern , example: I'm walking at a rate of 2 miles an hour.

Ratio is related to the proportion of two or more objects, example: The ratio for a perfect tang juice is 1 packet of tang dust thingy for 1.5 liters of water.

Hope it helps :)
