Solve for t<br><br> 4/3 = t/7

Mumz [18]

Answer:

$\frac{28}{3}=t$

Step-by-step explanation:

$\frac{4}{3}=\frac{t}{7}$

Use cross products to simplify the equation. Multiply the denominator of the second fraction by the numerator of the first fraction, and the denominator of the first fraction by the numerator of the second,

$(4)(7) = (3)(t)$

Simplify,

$28=3t$

Inverse operations,

$\frac{28}{3}=t$
