Ta thấy:
15/16 = 1/16+(1/16+1/16)+(1/16+1/16+1/6+1/16)+(1/16+1/16+1/16+1/16+1/16+1/16+1/16+1/16)
=1/16+2/16+4/16+8/16 =1/16+1/8+1/4+1/2

Ta thấy:
15/16 = 1/16+(1/16+1/16)+(1/16+1/16+1/6+1/16)+(1/16+1/16+1/16+1/16+1/16+1/16+1/16+1/16)
=1/16+2/16+4/16+8/16
=1/16+1/8+1/4+1/2

\(\frac{15}{16}=\frac{1}{16}+\frac{1}{8}+\frac{1}{4}+\frac{1}{2}\)

15 / 16 = 1 / 8 + 1/2 + 1/4 + 1/ 16
tích đúng cho mình nha

câu 1 15/16= 1/16+[1/16+1/16]+[1/16+1/16+1/16+1/16]+[1/16+1/16+1/16+1/16+1/16+1/16+1/16+1/16]
=1/16+1/2+1/4+1/8

A=1/12+1/8+1/24+1/16
A=5/16
A=5x3/16x3
A=15/48
=> A dưới dạng một phân số có mẫu số là 48 thì tử số của phân số đó là 15
k cho minh
\(\frac{15}{16}=\frac{1}{16}+\frac{1}{16}+\frac{1}{16}+....+\frac{1}{16}\) (15 SỐ HẠNG)
\(\frac{1}{2}\)+\(\frac{1}{4}\)\(\frac{1}{16}\)+\(\frac{1}{16}\)+\(\frac{1}{16}\)
