Question

Guys, Help me. In a 5th grade math problem, It says, “Find the Unknown Number”, And the problems are ?/2 x 8=4. ?x 5/6= 20/6, Or 3 and 1/3. And the last problem, 1/? X 18=3
I need answers under a day and...Just please help, I don’t know how to solve this.

Answer 1

When you're multiplying fractions by a whole number, flip the equation around. For the first one, ?/2x8=4 can be converted to 8/2=4. Or half of 8 is 4.

The next one is missing the whole number. It converts to 20/6 / 5/6, which is equal to 20/5 and 6/6, which is 4/1 or 4.

The last question can be converted to 18/3=?, which is 6. So the answer to that one is 1/6 x 18=3.

1. 1/2 x 8 = 4

2. 4 x 5/6 = 20/6

3. 1/6 x 18 = 3
