How do you solve 2/5g=3/5 with a whole number??? I'm stuck
Blababa [14]

Answer:

g = 3/2

Step-by-step explanation:

Step 1: Multiply both sides by 5 (the whole number).

  • \frac{2}{5}g * 5 = \frac{3}{5}  * 5
  • 2g = \frac{15}{5}
  • 2g = 3

Step 2: Divide both sides by 2.

  • 2g/2 = 3/2
  • g = 3/2

Therefore, g = 3/2.

Have a lovely rest of your day/night, and good luck with your assignments! ♡
