Answer: Jessie still has 3/10 left.
Step-by-step explanation:
Convert 2/5 into tenths by multiplying by 2.
2/5 x 2 = 4/10
3/10 + 4/10 = 7/10
The entirety of her homework is 10/10 so do
10/10 - 7/10 = 3/10
She has 3/10 left.
You can write the expression by reading it step by step. “The quotient of 10 and a number (x)” means 10/x. “Increased by 6” means +6. So, the expression is: 10/x+6 or (10/x)+6 to makes it easier to look at. Hope this helped!
