How do you divide fractions???
Cross multiply:
For example, 4/5 divided by 6/7 would be 28/30 or 14/15.
3/4 divided by 2/3 would be 9/8 or 1 and 1/8
Actually, the word cross multiply is a misnomer. What is being done is multiplying by the reciprocal
for instance 4/5 divide by 6/7 is the same as 4/5 multiplied by 7/6
3/4 divided by 2/3 is the same as 3/4 multiplied by 3/2
Both 14/15 and 9/8 are correct for the examples given; however, I don't call that cross multiplying.To divide fractions, invert the deonimator and multiply.
(4/5)/(6/7) = (4/5)*(7/6)=28/30=14/15
(3/4)/(2/3) = (3/4)*(3/2)= 9/8.
(3/4 : 4/5)x 4/6
.06 divided by 7.1
15/4:5/3
2/5 × 3/9
Ah, I see what you're saying! It's like saying "cross multiply" when what we're really doing is multiplying by the reciprocal. It's like telling a joke and then explaining it, just to make sure everyone's on the same page. "Hey, why did the fraction go to the therapist? It had an identity crisis! See, it's funny because the fraction was confused about who it was!" Anyway, thanks for the clarification. Keep those math questions coming!
To divide fractions, you need to follow these steps:
1. Take the reciprocal of the second fraction (the one you want to divide by). To do this, swap the numerator and denominator.
2. Multiply the first fraction by the reciprocal of the second fraction.
3. Simplify the resulting fraction if possible.
For example, let's divide 4/5 by 6/7:
1. The reciprocal of 6/7 is 7/6.
2. Multiply 4/5 by 7/6: (4/5) * (7/6) = 28/30.
3. Simplify the resulting fraction: 28/30 can be simplified to 14/15.
So, 4/5 divided by 6/7 is 14/15.
Another example, let's divide 3/4 by 2/3:
1. The reciprocal of 2/3 is 3/2.
2. Multiply 3/4 by 3/2: (3/4) * (3/2) = 9/8.
3. The resulting fraction, 9/8, cannot be simplified any further.
So, 3/4 divided by 2/3 is 9/8, which is equivalent to 1 and 1/8.
Remember, when dividing fractions, you are essentially multiplying by the reciprocal.
