I hope this helps5. Find the equivalent fractions.⅔ = ….. = …..⅕ = ….. = …..Which one is the greater fraction?¾ or ⅙ The greater is …..⅖ or ½ The greater is …..Which one is the smaller fraction?⅔ or ⅚ The smaller is …..3/7 or ½ The smaller is …..
Jawab:
Penjelasan dengan langkah-langkah:
⅔ = 4/6 = 8/12
⅕ = 2/10 = 4/20
3/4 = 3 : 4 = 0,75
1/6 = 1 : 6 = 0,16
So , 3/4 is the greatest.
2/5 = 2 : 5 = 0,4
1/2 = 1 : 2 = 0,5
So, 1/2 is the greatest.
2/3 = 2 : 3 = 0,66
5/6 = 5 : 6 = 0,83
So, 2/3 is the smallest.
3/7 = 0,42
1/2 = 0,5
3/7 is the smaller

14. four decimal fraction that are smaller than 0.5
Jawaban:
2/5 = 0,4
2/5 = 0,43/10 = 0,3
2/5 = 0,43/10 = 0,31/5 = 0,2
2/5 = 0,43/10 = 0,31/5 = 0,21/10 = 0,1
Penjelasan dengan langkah-langkah:
four decimal fraction that are smaller than 0,5
empat desimal pecahan yang lebih kecil dari 0,5
Step 1:Four decimal fraction that are smaller than 0,5 is:
0,4
0,3
0,2
0,1
Step 2:Convert to fraction
0,4 = 4/10 = 2/5
0,3 = 3/10
0,2 = 2/10 = 1/5
0,1 = 1/10
From that we know if four decimal fraction that are smaller than 0,5 is:
Answer:
2/5 = 0,4
2/5 = 0,43/10 = 0,3
2/5 = 0,43/10 = 0,31/5 = 0,2
2/5 = 0,43/10 = 0,31/5 = 0,21/10 = 0,1

20. 31/80 fraction as a decimal
Jawaban :0,3875Penjelasan :
31 / 80 = 31 : 80 = 0,3875
31/80 = 0.3875
Penjelasan dengan langkah-langkah
Pecahan Desimal (Decimal Fraction)
Note that 80 × 125 = 10000.
Thus,
31/80 = (31×125) / (80×125)
31/80 = [(30+1)×125) / 10000
31/80 = (3750+125) / 10000
31/80 = 3875 / 10000
∴ 31/80 = 0.3875 (answer)
