Is there anything that can help me understand this without me forgetting to flip the fraction or cancel out the numbers and all that...?

Hi Maddy. To which concept are you referring? Dividing fractions? - Ms. J
ReplyDeleteYou see, I'm getting confused between dividing fractions and multiplying fractions. I stay after school sometimes w/ Mrs.Croskey and it comes back to me but then for homework the next day, I sometimes won't be able to get through it without having my dad help me. The worksheet she gave us for the weekend I'm fine with. To be honest she said to do the Odds only and I did all of them on accident �� Anyway if you have : 3/4 ➗ 2/4 I don't understand how to get the answer. Would you flip 2/4 and cancel out and multiply across or cross multiply or just divide it? My brain is sad because I don't know, can you help me Ms.J???
ReplyDeleteHave no fear Miss Maddy. It will become easier the more you practice. I can't see the symbol between those two fractions up there - it just looks like a box. But if it's a division symbol,
Delete3/4 divided by 2/4 - then yes. Two simple steps.
1) Flip the second fraction.
2) Multiply the fractions instead of divide.
So, after we do those two steps, our new problem is:
3/4 x 4/2
Now, since we're multiplying (if we were adding we'd have to change them to equivalent fractions, but thankfully we're not! :) - we can just multiply the tops:
3 x 4 = 12
And the bottoms:
4 x 2 = 8.
So our new fraction is 12/8. We simplify this to 1 and 1/3.
Does that help? Let me know. Otherwise I'll try to draw something that might help you understand visually.
Mrs. Johnson, I am confused for number 63. I am drawing a blank and I am confused of how you would do that. also, are we allowed to use our calculators on the final? Thx,

yes its a division symbol, and yes it helps a lot, Thank you
