Jawab pake jalan Ya.,,, plis

1.) 4 2/5 - 1 1/5 + 2 3/4
= 22/5 - 6/5 + 11/4
= 88/20 - 24/20 + 55/20
= 119/20 = 5 19/20
2.) 2,25 + 25% + 1 1/2
= 2,25 + 0.25 + 1,5
= 4


maaf klo salah:)

1. 22/5-9/5+11/4=88/20-36/20+55/20
=88/20-91/20
=-3/20
2. 225/100+25/100+3/2 =225/100+25/100+150/100
=250/100+150/100
=400/100
=4
