Cross Multiplication Worksheet Multiplication Worksheets When you’re comparing two groups and you know one actual value, cross multiplication is usually the most direct strategy. for example: if the ratio of cups to plates is 2 to 3, and there are 12 plates, how many cups are there? start by writing the ratio as two fractions and then cross multiply. 2 3 2 3 2× 12 24 8 = c p = c 12 = c ×3 = 3c = c. If we apply the cross multiplication method, we get 24 days 15 workers x days 40 workers x = \frac {24\times40} {15} this results in 64, implying that 40 workers take 64 days. this is logically not right, since 40 workers are taking more days than 15 workers. i would recommend solving the problem using the work formula i.e work = rate. Another method for comparing fractions is cross multiplication. consider the two fractions in the example above, 3 7 and 7 14. Rationalization of surds: in order to rationalize a given surd, multiply and divide by the conjugate of denominator [conjugate of (a √ b) is (a– √ b) and vice versa].

Rationalization of surds: in order to rationalize a given surd, multiply and divide by the conjugate of denominator [conjugate of (a √ b) is (a– √ b) and vice versa]. Cross multiplying assumes there is an equality between the two expressions, when the whole point of this type of problem is determine the nature of the relationship between the two expressions. 4.7 cross multiplication (1:55) . In mathematics, specifically in elementary arithmetic and elementary algebra, given an equation between two fractions or rational expressions, one can cross multiply to simplify the equation or determine the value of a variable. Here are some tips that will help you do math by hand quickly and accurately. while these tips will help you on the entire test, you’ll get the most out of them on the quantitative comparison section. 1. cross multiply two fractions to compare them. which fraction is bigger?.
