2/5 : 1/4 x ( 40% + 1/2 )​

Jawaban:

2/5 ÷ 1/4 × ( 40% + 1/2 ) :

= ( 40% + 1/2 )

= 40/100 + 1/2

= 40/100 + 50/100

= 90/100

2/5 ÷ 1/4 × 90/100

= 2/5 × 4/1 × 90/100

= 8/5 × 90/100

= 720/500

= 144/100

= 36/25

Jawab:

2/5 : 1/4 x ( 40% + 1/2 ) = 2/5 x 4/1 x (0,4 + 1/2) = 4/5 x  0,9 = 4/5 x 9/10 = 36/50 = 18/25
