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

To solve for t, we'll start by converting the mixed numbers into improper fractions:

2 3/4 = 11/4 4 1/8 = 33/8

Now we can rewrite the equation:

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

To divide fractions, we invert the second fraction and multiply:

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

Multiplying the fractions on the left gives:

88/132 = 1.6 / t

To solve for t, we'll cross multiply and then solve for t:

88t = 132 * 1.6 88t = 211.2

Dividing both sides by 88 gives:

t = 211.2 / 88 t = 2.4

So, t = 2.4.
