A.5 3/5 – 2 1/4=b.5 1/8 – 3 2/5=c.5 1/2 – 4 6/10=d.2 4/6 – 2 1/4=​

Jawab:

a. 5 3/5 – 2 1/4 = ( 5- 2 ) 3/5 – 1/4 = 3 ( 12/20 – 5/20 ) = 3 17/20

b. 5 1/8 – 3 2/5 = 41/8 – 17/5 = 205/40 – 136/40 = 69/40 = 1 29/40

c. 5 1/2 – 4 6/10 = 11/2 – 46/10 = 55/10 – 46/10 = 9/10

d. 2 4/6 – 2 1/4 = ( 2 – 2 ) ( 4/6 – 1/4 ) = 0 ( 8/12 – 3/12 ) = 5/12

Maaf klo salah

Semoga membantu ^_^
