Tlng di bantu yah.... 1. (1/2×3/5) + (1 - 4 1/3) =..... 2.7 2/3 × 5/5 =.....

1. (1/2 x 3/5) + (1- 4 1/3)
 = (3/10) + (1 - 13/3)
 = (3/10) + (-10/3)
 = 9/30 - 100/30
 = -91/30 = -3 1/30
2. 23/3 x 5/5
= 23/3 x 1
= 23/3
= 7 2/3

1) 1/2×3/5=3/10
1 - 4 1/3=1-13/3 = -10/3 =3 1/3
3/10 + -3 1/3= 3/10 + -10/3= -91/30 = -3 1/30
2) 7 2/3×5/5= 23/3×1=23/3=7 2/3
