Penjelasan dengan langkah-langkah:
NO 1
=7/10+2/3÷5/6
=7/10+(2/3×6/5)
=7/10+4/5
=7/10+8/10
=15/10=3/2=1 1/2
B
NO 2
=1 3/7×2 1/3-3 1/2
=(11/7×7/3)-7/2
=11/3-7/2
=22/6-21/6
=1/6
=A
Jawaban:
9. 7/10 + 2/3 : 5/6 = 7/10 + 2/3 x 6/5
= 7/10 + 12/15
samakan penyebut
= 21/30 + 24/30
= 45/30
= 1 15/30
= 1 1/2
jadi, jawabannya b. 1 1/2
10. 1 3/7 x 2 1/3 - 3 1/2 = 10/7 x 7/3 - 7/2
= 70/21 - 7/2
samakan penyebutnya = 140/42 - 147/42
= -7/42
= - 1/6
jadi, jawabannya d. -1/6
semoga bisa membantu
