Bubbles has painted 2/5 of her bedroom wall.after paintibg 1/4of the painted portion how much more does she need to finish painting her wall?
It would help if you would proofread your work before you post it.
There is no indication of amount of paint used.
In terms of the walls, 1 - .4 - .25 = ?
assuming you meant to say
"after painting 1/4 of the unpainted portion"
then we have2/5 painted, so 3/5 unpainted
1/4 * 3/5 = 3/20
2/5 + 3/20 = 8/20 + 3/20 = 11/20
so 9/20 remains unpainted
To find out how much more Bubbles needs to finish painting her wall, let's break down the problem step by step:
Step 1: Calculate the total painted portion of the wall. Bubbles has painted 2/5 of the wall.
Step 2: Calculate 1/4 of the painted portion. To find 1/4 of 2/5, multiply the numerator (2) by 1 and the denominator (5) by 4. This gives us 2/20.
Step 3: Determine how much more Bubbles needs to finish painting her wall. Subtract the portion already painted (2/5) by the portion painted on Step 2 (2/20).
2/5 - 2/20 = (8/20) - (2/20) = 6/20
Therefore, Bubbles needs to paint an additional 6/20 (or simplifying it, 3/10) of her wall to complete the painting.
To find out how much more Bubbles needs to finish painting her wall, we need to subtract the portion she has already painted from the total wall area.
1. First, let's determine the fraction of the wall that Bubbles has already painted. We are told that she has painted 2/5 of her bedroom wall.
2. Next, let's find out how much she has painted after painting 1/4 of the painted portion. To do this, we multiply 2/5 by 1/4.
(2/5) * (1/4) = 2/20 = 1/10
So, Bubbles has painted an additional 1/10 of her bedroom wall.
3. Now, to find out how much more she needs to finish painting the wall, we subtract the portion she has already painted (1/10) from the total wall area.
Total wall area - Portion already painted = Remaining portion
1 - 1/10 = 10/10 - 1/10 = 9/10
Therefore, Bubbles still needs to paint 9/10 (nine-tenths) of her bedroom wall to finish it.
