solve for u. \$\\frac{u}{7} = 11.2\$ \$u = \\square\$

$solve for u. \$\\frac{u}{7} = 11.2\$ \$u = \\square\$$

solve for u.
\$\frac{u}{7} = 11.2\$
\$u = \square\$

To isolate $ u $, we multiply both sides of the equation $ \frac{u}{7} = 11.2 $ by 7. This gives us $ u = 11.2 \times 7 $.

Now, we calculate $ 11.2 \times 7 $. $ 11.2 \times 7 = 78.4 $.

$ u = 78.4 $
