Jawaban:
1) 3/5 + 4 9/10 - 1/3
= ( 3/5 + 4 9/10 ) - 1/3
= ( 6/10 + 4 9/10 ) - 1/3
= 55/10 - 1/3
= 165/30 - 10/30
= 155/30 ( Dibagi dengan 5 )
= 31/6
= 5 1/6 ✅
2) 11/6 - 1 3/4 + 5/3
= 11/6 - 7/4 + 5/3
= 22/12 - 21/12 + 20/12
= 21/12
= 1 9/12
= 1 3/4 ✅
3) 10/8 + ( 5 2/5 - 5/2 )
= 10/8 + ( 27/5 - 5/2 )
= 10/8 + ( 54/10 - 25/10 )
= 10/8 + 29/10
= 50/40 + 116/40
= 166/40
= 83/20
= 4 3/20 ✅
4) 6/5 : 1/6 × 7/5
= 6/5 × 6/1 × 7/5
= 36/5 × 7/5
= 252/15
= 10 2/25 ✅
5) 5/8 × ( 1/7 : 3/2 )
= 5/8 × ( 1/7 × 2/3 )
= 5/8 × 2/21
= 10/168
= 5/84 ✅
6) 8/5 × 4/3 : 2 1/7
= 8/5 × 4/3 ÷ 15/7
= 8/5 × 4/3 × 7/15
= 8 × 4 × 7 / 5 × 3 × 15
= 33 × 7 / 15 × 15
= 224/225 ✅
7) 11/2 × 3/5 + 4 1/5
= 11/2 × 3/5 + 21/5
= 33/10 + 42/10
= 75/10
= 15/2 ✅
8) ( 100/28 - 21/7 ) × 3 1/2
= ( 100/28 - 84/28 ) × 3 1/2
= 16/28 × 3 1/2
= 16/28 × 7/2
= 8/4 × 1/1
= 8/4
= 2/1 ✅
9) 5/7 : 3/5 + 7 1/42
= ( 5/7 × 5/3 ) + 7 1/42
= 25/21 + 7 1/42
= 50/42 + 7 1/42
= 121/42 ✅
10) ( 7/36 + 11/9 ) : 2 2/9
= 7/36 + 44/36
= 51/36 : 2 2/9
= 51/36 × 9/20
= 459/720 ✅
