• What is the reciprocal?
• A reciprocal of a fraction is when you flip the numerator and denominator. Such as the reciprocal of 6/10 is 10/6.
• wait, why is two fourths the same as eight fourths?
• 2/4 is not the same as 8/4 but 4/2 is the same as 8/4
• how would you do this if the mixed number was negative
• help! how do i take a fraction like point five over three, and divide the point five by the three. oh and its minus point five.
• -0.5/3 = -5/30, then just use long division method or use -5/30 times 1/10 instead, it's easier (you fan divide without the negative sign and put it back in the answer)
• How do I do an equation like: 5/-8 ÷ 1 3/7, with a negative denominator? Please answer this ASAP, I really need help with this.
• You can always do the signs apart from the numbers. In multiplying and dividing, you count number of negative signs. With 0, 2, 4, 6, ... answer is positive, if 1, 3, 5, 7, ... answer is negative. In your example, you only have 1 negative, so answer is negative then do (5/8)/(1 3/7).
• Can you show me how to do this problem? 4 1/2 divided by 3? I don't get it.
• 4 1/2 divided by 3 = 9/2 times 1/3 = 3/2 or 1 1/2
• 5+4(8-4)+10/2
• 5+4(8-4)+10/2
5+4(4)+10/2
5+16+10/2
5+16+5
=26

*26 is the answer. Hope this helps.
• The heck is that black magic at the start
• 2x4+1
• but how do I divide negative numbers?
• Note: These rules for dividing also apply for multiplication

A negative divided by a positive is a negative

A positive divided by a positive is a positive
