Question

1) 3/8y=2,25 2) 8,4:x=2(целых) 3) x:5/9=3,6

Answer 1

1)3/8y=2,25
y=2,25:0,375
y=6
2)8,4:x=2
x=2*8,4
x=16,8
3)x:5/9=3,6
x=36/10*5/9
x=2

Answer 2

1. To solve for y in the equation 3/8y = 2.25, we can multiply both sides by the reciprocal of 3/8, which is 8/3: 3/8y * 8/3 = 2.25 * 8/3 y = 6

Therefore, the solution is y = 6.

2. To solve for x in the equation 8.4/x = 2, we can multiply both sides by x: 8.4/x * x = 2 * x 8.4 = 2x x = 4.2

Therefore, the solution is x = 4.2.

3. To solve for x in the equation x/(5/9) = 3.6, we can multiply both sides by the reciprocal of 5/9, which is 9/5: x/(5/9) * 9/5 = 3.6 * 9/5 x = 6.48

Therefore, the solution is x = 6.48.
