Help Me~ Random Math Question


KLC77

Recommended Posts

My niece needs help with her math packet for school and I'm the only one who knows anything about math in my family. Only problem is I can't remember if I know how to divide fractions correctly.

 

Do you just multiply by the reciprocal? For example 2/3 divided by 3/8 would be 2/3 times 8/3 equalling 16/9? Does that even make sense? lol Ugh, 7th grade math! TIA

That is exactly right!

 

Dividing Proper/Improper Fractions

dividend ¸ divisor = quotient

 

1. Change mixed numbers to improper fractions.

 

2. Change the dividing sign to multiply and flipflop (take the reciprocal of) the divisor.

 

3. Multiply the numerators and multiply the denominators

 

4. Change to mixed numbers if necessary.

 

5. Reduce to lowest terms.

OMG I almost broke out in a sweat. I swear I know nothing about math (it was my worth subject) which is why I became a lawyer. I'm pretty sure you multiply by the recipricol but knowing my pathetic 83 in 7th grade math I'm more likely than not wrong. Hopefully someone who is good at math like Christa or Ann can help you out.

    • Hi everyone! I have been doing lots of research on various wedding venues all around Mexico, my fiance wants a destination wedding and I am happy to have a wedding wherever so long as the vibe is right and guests are happy!  I have been seriously looking at Cabo Azul and was trying to find potential costs for them, but only found a page about their wedding costs from 2010. Does anyone have any updated information on costs / reviews they would like to share of this venue? Or advice in general, anything helps. Thanks so much, happy wedding planning to all!
    • Hello everyone, I am dreaming of a wedding in Costa Rica and was wondering if I could get any help with venues and wedding planners. I am thinking Tamarindo because a close friend of mine lives there and I've been in town more than a couple of times, she's being helpful but is at a loss when it comes to this subject really so I was wondering if anyone here had recommendations. I am not closed to other town suggestions either, if I happen to find a good place and staff somewhere else. These are the places I have so far, has anyone had any experience with any of them?  Stay In Tamarindo Luxury Villas in Costa Rica Luxury Villas Pinilla Tropical Homes of Costa Rica The Point Luxury Villa Thank you so much for your help!
