Insturctions to care for a plant say to water it with 3/4 cup of water every day.The plant has been getting 25% too much water.

disa [49]

For this case we propose a rule of three. We assume that the excess water received was in one day. So:

$\frac {3} {4}$ cup ------> 100%

x ----------------------------> 25%

Where "x" represents excess water.

$x = \frac {25 * \frac {3} {4}} {100}\\x = \frac {\frac {75} {4}} {100}\\x = \frac {75} {400}\\x = \frac {15} {80}\\x = \frac {3} {16}$

Thus, the excess water is $\frac {3} {16}$ cups.

Then, in one day you receive in total:

$\frac {3} {4} + \frac {3} {16} = \frac {16 * 3 + 4 * 3} {16 * 4} = \frac {48 + 12} {64} = \frac {60 } {64} = \frac {15} {4}$ cups of water.

Answer:

$\frac {15} {4}$ cups of water
