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

To solve the equation 2 3/4 ÷ 4 1/8 = 1.6 ÷ t, we need to convert all the quantities to improper fractions and then solve for t:

2 3/4 = (2 * 4 + 3) / 4 = 11/4

4 1/8 = (4 * 8 + 1) / 8 = 33/8

Now, we have 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

(11 * 8) / (4 * 33) = 1.6 ÷ t

88 / 132 = 1.6 ÷ t

Now, we can cross-multiply:

88t = 1.6 * 132

88t = 211.2

Divide both sides by 88:

t = 211.2 / 88

t ≈ 2.4

Therefore, the value of t that satisfies the equation is approximately 2.4.
