2 3/4 /4 1/8= 1,6 / t

To solve this equation for t, we can cross multiply and then solve for t.

First, let's convert the mixed numbers to improper fractions:

2 3/4 = (24 + 3)/4 = 11/4 4 1/8 = (48 + 1)/8 = 33/8

Now we can rewrite the equation:

(11/4) / (33/8) = 1.6 / t

To simplify, we can multiply both sides by the reciprocal of (33/8):

(11/4) * (8/33) = 1.6 / t

Now multiply the numerators together and the denominators together:

(11 * 8) / (4 * 33) = 1.6 / t

88/132 = 1.6 / t

Now we can cross multiply:

88t = 132 * 1.6

88t = 211.2

Finally, divide both sides by 88 to solve for t:

t = 211.2 / 88

t ≈ 2.4
