Cross multiplication can help speed up a solution. Like in this example:Example: Find "x" in x 8 = 2 x Start with: x 8 = 2 x Cross multiply:x2 = 8 × 2 Calculate:x2 = 16 And solve:x = 4 or −4 Check: Does 4 8 = 2 4 and −4 8 = 2 −4 ?
Perform cross multiplication The side with the highest result is the larger fraction The very first step is to perform the cross multiplication. Using the same example as shown earlier in the lesson, this is what happens. Cross multiplication Performing the multiplications, this is the result. {...

Cross multiplication involves the multiplication of two fractions set equal to each other and is used to solve for an unknown number. If the fraction a/b is set equal to x/y, the "b" and "x" can be multiplied together, as can the "a" and "y." This works because multiplying a fra...
Further Example. 6y 7 x 8 = y = 56 6 y = y = Solve : (1) Cross multiply the y term first. (2) Solve as normal. 6y 7 x 8 = y = 56 6 y = y = What Goes in The Box ? Solve the following equations using cross multiplication or equivalent fractions. (1) (4) x = 2 ...
I What is the purpose of cross multiplication in vector multiplication? Hi, what does it mean to cross multiply two vectors? I couldn't imagine them in real life. eg Force vector. Multiplying Force vector to a scalar value means you multiple the 'Strength' of the force, Dot multiplication...
If linear gain is used (scale: linear), the gain value is treated as a simple multiplication factor. A factor 0.5 attenuates by a factor two (equivalent to a gain of -6.02 dB). A negative value inverts the signal. Note that the invert setting also inverts, so a gain of -0.5 with...
