1⅗ + ⅔
= ( 1.5 + 3 )/5 + ⅔
= ( 5 + 3 )/5 + ⅔
= 8/5 + ⅔
= ( 8 × 3 )/( 5 × 3 ) + ( 2 × 5 )/( 3 × 5 )
= 24/15 + 10/15
= ( 24 + 10 )/15
= 34/15
= 2 + 4/15 atau 2,2666.. atau 226,66..% atau 34/15
⅚ × 9/20
= ( 5 × 9 )/( 6 × 20 )
= 45/120
= ( 45 ÷ 5 )/( 120 ÷ 5 )
= 9/24
= ( 9 ÷ 3 )/( 24 ÷ 3 )
= ⅜ atau 0,375 atau 37,5% atau 0⅜

Soal Nomor 1
1⅗ + ⅔
= ( 1.5 + 3 )/5 + ⅔
= ( 5 + 3 )/5 + ⅔
= 8/5 + ⅔
= ( 8 × 3 )/( 5 × 3 ) + ( 2 × 5 )/( 3 × 5 )
= 24/15 + 10/15
= ( 24 + 10 )/15
= 34/15
= 2 + 4/15 atau 2,2666.. atau 226,66..% atau 34/15
Soal Nomor 2
⅚ × 9/20
= ( 5 × 9 )/( 6 × 20 )
= 45/120
= ( 45 ÷ 5 )/( 120 ÷ 5 )
= 9/24
