\(a,2=\dfrac{?}{7}\Rightarrow?=2\times7=14\\ b,4=\dfrac{?}{5}\Rightarrow?=4\times5=20\\ c,3=\dfrac{18}{?}\Rightarrow?=18:3=6\\ d,12=\dfrac{?}{4}\Rightarrow?=12\times4=48\)
A) 2 = 14/7
B) 4 = 20/5
C) 3 = 18/6
D) 12 = 48/4
A) 2 = \(\dfrac{14}{7}\)
B) 4 = \(\dfrac{20}{5}\)
C) 3 = \(\dfrac{18}{6}\)
D) 12 = \(\dfrac{48}{4}\)
