Answer in detail. Two students had to multiply the same number by 18 for the first one and by 31 for the second one. The first student got 1296 as the answer. What number did the second student get as the answer?

To solve this problem, you can use a proportion. A proportion is an equality of two ratios. You can write the proportion as follows:

18 x = 1296 31 x = y {\\displaystyle {\\frac {18x}{1296}}= {\\frac {31x}{y}}}

To find the value of y, you can cross-multiply and solve for y:

18 x y = 31 x 1296 y = 31 x 1296 18 x y = 2232 x {\\displaystyle \\begin{aligned}18xy&=31x1296\\\\y&= {\\frac {31x1296}{18x}}\\\\y&=2232x\\end{aligned}}

Since you know that the first student got 1296 as the answer, you can plug in x = 1296 18 = 72 {\\displaystyle x= {\\frac {1296}{18}}=72} and find the value of y:

y = 2232 x y = 2232 ( 72 ) y = 160704 {\\displaystyle \\begin{aligned}y&=2232x\\\\y&=2232(72)\\\\y&=160704\\end{aligned}}

Therefore, the second student got 160704 as the answer.how to solve a proportion problem
