The answer is 63 because you have set up the proportion 1.5 over 3 = 31.5 over x and then you cross multiply 31.5 times 3 and you get 94.5 then you divide that by 1.5 and you get 63.
<span>Think of of the colon ( : ) as a fragment bar. that's all that's! So here is the project now: 2 / 5 = 4 / ? think of of the ( ? ) as a variable (so, replace it with "x" for now to make issues much less stressful). So... 2 / 5 = 4 / x Now you bypass multiply to create an equation which will enable you to remedy for x (or the ? mark). (word: the --- is the fraction bar, overlook with regard to the ..... they are used as fillers so the textual content textile will exhibit suitable). 2.......4 --- = --- 5.......x So, multiply 2 and x, placed that answer on the left edge of the equation (which ability = sign). Then, multiply 5 and four, then placed that on the best edge of the equation (back, which ability the = sign). So now... 2x = 20 Divide the two components by using 2, then you somewhat get x = 10 So, x = ( ? question mark) And the ratio is two:5 = 4:10
