Answer: 1200 pennies

Step-by-step explanation:

Let x be the number of pennies Yoko's bank can hold.

We can set up an equation representing the information given.

$\frac{2x}{5} + 320 = \frac{2x}{3}$

We can multiply both sides by 15:

6x + 4800 = 10x

Combine like terms:

4x = 4800

Divide both sides by 4:

x = 1200

7/8+9/10=71/40=1 31/40
1/4+2/3=11/12
1/2+1/4 is different from 1/2+1/3 because
1/2+1/4= 2/4+1/4= 5/1 =1 1/4
1/2+1/3=3/6+2/6=5/6
