Question

resuelve las siguientes multiplicasiones de fracciones 9/4×8/2= 6/8×5/9= 5/3×3/8= 5/3×6/2= 5/9×7/10= 6/8×5/3= ayuda plis ​

Answer 1

9/4 × 8/2

= 9/4 × 4 = 9/4 × 4/1

= 9/1 = 9

6/8 × 5/9

= 3/4 × 5/9 -{ m.c.m de 9 = 3 * 3

= 3 × 5/4 × 3 × 3

= 5/4 × 3

= 5/12

5/3 × 3/8 -{ simplificar

= 5/8

5/3 × 6/2 -{ simplificar

= 5/3 × 3 = 5/3 × 3/1 -{simplificar

= 5/1 = 5

5/9 × 7/10 -{ m.c.m de 10 = 5 * 2

= 5 × 7/9 × 5 × 2 -{ simplificar

= 7 /9 × 2

= 7/18

6/8 × 5/3 -{ simplificar

= 3/4 × 5/3 -{ simplificar

= 5/4
