1 / 8 × 14 ÷ 7 / 8
=1/8x14x8/7
=1/8x16
=2
(4 / 5 + 3 / 10) △ 3 / 10
=4/5x10/3+3/10x10/3
=8/3+1
=11/3
3 / 4 / 15 / 16 / 5 / 6
=3/4x16/15x6/5
=4/5x6/5
=24/25
4 / 5 △ 7 / 4-3 / 7 × 4 / 5
=4/5x4/7-4/5x3/7
=4/5x(4/7-3/7)
=4/5x1/7
=4/35
(1 / 3 * 6 / 7-1 / 4) / 5 / 14 = (simple calculation)
(1 / 3 * 6 / 7-1 / 4) / 5 / 14
=2/7x14/5-1/4x14/5
=4/5-7/10
=8/10-7/10
=1/10

=(88-11/80)×5/11
=88×5/11-11/80×5/11
=40-1/16
=39 and 15 / 16
Simple operation of 7 / 8 / 9 * 8 / 15
7 / 8 / 9 * 8 / 15
=7 out of 9 * 8 out of 5 * 8 out of 15
=7 / 9 × 64 / 3
=7 / 3 × 64
=448 out of 3
The reciprocal of true fraction must be greater than 1. The reciprocal of false fraction must be true fraction. 1 divided by a equals B and B must be reciprocal
The reciprocal of the true fraction must be greater than 1.. (right)
The reciprocal of a false fraction must be a true fraction
1 divided by a equals B and B must be reciprocal. (wrong) when a equals 0, the formula does not hold
If 7 / A is a false fraction and 8 / A is a true fraction, then a should be () A. greater than 7, B. equal to 7, C. less than 7
B
4 x minus 2 minus 6 2x minus 1 equals 1
Take 12 on both sides
3(x-2)-2(2x-1)=12
3x-6-4x+2=12
4x-3x=12+2-6
x=8
X minus ten sixths plus one equals two fourths plus one, and finally minus one
H urgent
x-(10x+1)/6=(2x+1)/4-1
24x-4(10x+1)=6(2x+1)-24
24x-40x-4=12x+6-24
28x=14
x=1/2
What is 2 / 3 times 6 / 7 plus 2 / 3 divided by 1 / 7
It turns out to be five and five out of 21
Ax three quarters = BX two fifths, a: B is written as the simplest integer ratio is (), the ratio is ()
8: Eight out of fifteen
