Quarter (x + 5) = 12.5 (half x-0.4) △ one fifth = 53

Quarter (x + 5) = 12.5 (half x-0.4) △ one fifth = 53

Quarter (x + 5) = 12.5
x+5=12.5×4
x+5=50
x=45
(half x-0.4) △ one fifth = 53
Half x-0.4 = 53 × one fifth
Half x-0.4 = 10.6
x-0.8=21.2
x = 22

Four out of seven - x = half how to solve the equation

Four out of seven - x = one in half
transposition
X = 4 / 7 - 1 / 2
X = one fourteenth

Solve the equation {half x-one-third y = 1} {negative one-third X-Y = 2}

{1/2x-1/3y=1 ①
-1/3x-y=2/3 ②
① *6
3x-2y=6 ③
②*3
-x-3y=2 ④
③+④*3
-11y=12
y=-12/11
Substituting (4)
-x+36/11=2
x=14/11
The solution of the equation is
{14/11
y=-12/11

Ma Xiaohu is a careless child. When he does a division formula, he takes 5 / 6 of the divisor as 5 / 8 of the divisor, and the result is 120, which is not true

The correct results are as follows
120×5/8÷5/6=90

What is the sum of the product of one-half and two-thirds and three tenths
We need a formula

1/2x2/3+3/10=1/3+3/10=19/30

What's the quotient of four and a half times two-thirds minus one point five and dividing by zero point five?

3

A number, plus one-third, minus one-half, multiplied by three fifths, divided by four fifths, equals one sixteenth?
I can't get the number right several times, so I'd better make a list

1/16*4/5/3/5+1/2-1/3=3/12

Three fifths of a number is 16 more than half of it. What's the number?

Let this number be X
3/5x-1/2x=16
The solution is x = 160

Three fifths of a number is 16 more than one half of it
Three fifths of a number is 16 more than one half of it
The average number of the three trees is 21, and the ratio is 6:7:8. What are the three numbers?
12 minus the product of 21 / 5 and 5 / 3, and then divide by 5 / 2, how much is it?

Three fifths of a number is 16 more than one half of the number. 16 ^ (3 / 5-1 / 2) = 16 ^ (1 / 10) = 160. The average number of three trees is 21, and the ratio is 6:7:8. What are the three numbers? The sum of the three numbers = 21 × 3 = 636 + 7 + 8 = 2163 × 6 / 21 = 1863 × 7 / 21 = 2163 × 8 / 21 = 2412 minus five

What's the difference between the product of two 3 / 4 times minus the reciprocal of 8 / 3?

3/4×3/4-1÷（8/3）
=9/16-3/8
=3/16
A: the difference is 3 / 16
