Answer: A and E
Step-by-step explanation:
A. 21/25 × 50/63=
(21*50)/(25*63)=
21/63 * 50/25 =
1/3 * 2 =2/3
B. 7/8×9/25=
(7*9)/(8*25)=
63/200 [tex]\neq[/tex] 2/3
C. 1/30×2/3=
(1*2)/(30*3)=
2/90=
1/45 [tex]\neq[/tex] 2/3
D. 3/25×7/12=
(3*7)/(12*25)=
3/12 * 7/25 =
1/4 * 7/25 =
(1*7)/(4*25)=
7/100 [tex]\neq[/tex] 2/3
E. 20/27×27/30=
(20*27)/(27*30)=
27/27 * 20/30=
1 * 2/3 = 2/3
