Check this real life problem

Check different examples of number patterns. I don't know about you but I think there is magic in numbers.

 





CHECK YOUR KNOWLEDGE ON RATIONAL NUMBERS

Ok, so let's see if you master Rational Numbers. I know, I know....... Fractions are annoying and most people don't like them, but....  let's give them a chance










6th, 7th & 8th GRADE: Divide Fractions

MULTIPLICATIVE INVERSE


To divide fractions just multiply by its multiplicative inverse. In other words change the division sign to multiplication and then flip the second fraction. (Only the second fraction).
Another word use to describe multiplicative inverse is reciprocal

6th, 7th & 8th GRADE: Multiplying Fractions

When multiplying fractions, there are two ways you could do them.

1. Multiply both of the numerators then multiply both of the denominators, finally simplify if possible.

2. The second way is :  simplify before we multiply. When you have both fractions see if you can reduce them first before multiplying them. You could simplify vertically or across. Then multiply the reduced fractions.  Check this video to see an example.
