A recipe for cupcakes calls for 3 8 / 9 cups of flour. Jacob accidentally put in 4 1 / 6 cups. How many extra cups he put in.

En resumen

First we need to do that : 3 8 / 9 = (3x9 + 8) / 9 = 35 / 9 4 1 / 6 = (4x6 + 1) / 6 25 / 6 So he put accidentally : 25 / 6 - 35 / 9 MCM (6, 9) = 18 (25x3 - 35x2) / 18 = (75 - 70) / 18 It was 5 / 18 extra cups RPTA.

First we need to do that :

3 8 / 9 = (3x9 + 8) / 9 = 35 / 9

4 1 / 6 = (4x6 + 1) / 6 25 / 6

So he put accidentally : 25 / 6 - 35 / 9

MCM (6, 9) = 18

(25x3 - 35x2) / 18 = (75 - 70) / 18

It was 5 / 18 extra cups RPTA.
