Hey there!
“10 / k = 8 / 4”
FIRST: CROSS MULTIPLY
10(8) = 4(k)
10(8) = 80
4(k) = 4k
NEW EQUATION: 80 = 4k
SECOND: FLIP/TURN the EQUATION
4k = 80
THIRD: DIVIDE both SIDES by 4
4k / 4 = 80 / 4
CANCEL: 4 / 4 because that gives you 1
KEEP: 80 / 4 because that gives you the value of k
NEW EQUATION: 80 / 4 = v ; v = 80 / 4
FOURTH: SOLVE above and you have the k-value
Answer:
k = 5☑️
Good luck on your assignment and enjoy your day!
