Eva had 7/8 gallon of paint. Her brother Ivan used 1/4 gallon to paint his model boat. Eva needs at least 1/2 gallon to paint her bookshelf. Did Ivan leave her enough paint? Write an equation to solve.
7/8 - 1/4 = 7/8 - 2/8 = 5/8
so, what do you think?

Eva had 7/8 gallons of paint her brother Ivan used 1/4 of it Eva needs at least 1/2 gallons of paint a shelf is there enough paint left write an equation and fill the bar diagram.
To determine if Ivan left Eva enough paint, we need to subtract the amount of paint Ivan used from the amount Eva has and check if it is greater than or equal to the amount she needs.
First, we need to find out how much paint Eva has left after Ivan used some. We can subtract 1/4 gallon from 7/8 gallon using the concept of subtracting fractions with the same denominator.
7/8 - 1/4 = (7 - 2) / 8 = 5/8 gallon
Now, we can compare the amount Eva has left (5/8 gallon) with the amount she needs (1/2 gallon). We need to check if 5/8 is greater than or equal to 1/2.
To write this as an equation, we can use the greater-than-or-equal-to symbol (≥).
5/8 ≥ 1/2
So, the equation to solve is: 5/8 ≥ 1/2
