Direct link to Leon Tong's post “(Prepare for a long answe...” (Prepare for a long answer) Srivish, To answer your question, there IS another way to solve it. Cross multiplication. Here are some steps to help solve it However, if your Equation with variables, such as X, the whole question will change. In order to adapt to this, you will have to change the way you solve it. Here is a link detailing how to. (26 votes) sarathomsen24 6 years agoPosted 6 years ago.

Direct link to [sobbing mathematically]'s post “Because dividing is the s...” Because dividing is the same thing as multiplying by the reciprocal of a number. A reciprocal is basically just a number flipped upside down. Example: 4 ÷ 2 is the same thing as 4 * 1/2. (11 votes) Riley Kirshtner 5 years agoPosted 5 years ago.

Direct link to AllieM's post “A reciprocal is when you ...” A reciprocal is when you flip the numerator and the denominator to get it. So 2/4 would become 4/2, 5/6 would become 6/5, and so forth.

Direct link to David Severin's post “I think there is only one...” I think there is only one method, but it is shown or named in several ways. KCF (keep the first fraction, change the sign from / to *, and flip the second fraction) is a common mnemonic device to help remember what to do. The words are the same method of reciprocating the denominator and multiplying. (2 votes) LeafyMarinGurl (241259) a year agoPosted a year ago.

Direct link to Mr Levick's post “Same idea except this tim...” Same idea except this time the segment is larger than the initial amount. If we have segments of 7/3 (2 1/3) how many of them make 2/5. In this case you need less than one of them. 6/35 of one in fact. This is because 6/35 of 7/3 equals 2/5. (5 votes) CHIOMA WEBBER 5 months agoPosted 5 months ago.

1: First take your Equation, and if you've already written an answer. Erase it, then write a new set of brackets to have your fractions in.
2: Secondly, take your equation. Let's ignore that division sign for now. So you have your two pairs of fractions, Correct?
3: TO do this, you will have to multiply a bit. First, take the numerator of your first fraction, and multiply it with the denominator of the second Fraction. This will turn into your new Numerator. Now cross off the fractions you just used.
4: Following this, Take your remaining fractions and multiply. This will turn into your new denominator. And complete your answer.
