\(\frac{4}{7x31}+\frac{6}{7x41}+\frac{9}{10x41}+\frac{7}{10x57}\)
A= 4/7x31+6/7x41+9/10x41+7/10x57
Tính A
Giúp mik nhanh vs m.n!! Đang cần gấp. Sẽ tick cho ai nhanh nhất ^^
A= 4/7X31+6/7X41+9/10X41+7/10X57
B= 7/19X31+5/19X43+3/23X48+11/23X57
Tính A/B
A=4/7x31+6/7x41+9/10x41+7/10x57
B=7/19X31+5/19/43X3/23X43+11/23X57
Tính A/B
tìm tỉ số của A và B; A = 1/7x31 + 1/6x41 + 9/10x41 + 7/10x57; B = 7/19x31 + 5/19x43 + 3/23x43 + 11/23x57.
tìm tỉ số A/B
A= \(\frac{4}{7x31}+\frac{6}{7x41}+\frac{9}{10x41}+\frac{7}{10x51}\)
B= \(\frac{7}{19X31}+\frac{5}{19X43}+\frac{3}{23X43}+\frac{11}{23X57}\)
A = 4 / 7x31 + 6 / 7x41 +9 / 10 x41 + 7 / 10 x57
B = 7 / 19 x 31 + 5 / 19 x 43 + 3 / 23 x43 + 11 / 23 x 57
A/B = ????
