Answer:

1. How many hours did he practice in the first two days?

1.39/20 hours

2. What is the difference between his hours of practice on Tuesday and Monday

11/20

Step-by-step explanation:

On monday marco practiced the piano for 7/10 hour. On Tuesday he practiced for 1 1/4 hours each day write a question that involves adding or subtracting fractions

A follow up question to this will be ,

How many hours did Marco practice in the first two days?

on monday=7/10

Tuesday=1 1/4

7/10+5/4

lcm=20

(14+25)/20=39/20 hours

2. What is the difference between his hours of practice on Tuesday and Monday

We have to subtract his hours of practice on monday from Tuesday, since tuesday is greater

5/4-7/10

(25-14)/20

11/20

Step-by-step explanation:

Since we have given that

Number of hour Marco practiced the piano on Monday is given by

\frac{7}{10}

Number of hours Marco practiced the piano on Tuesday is given by

1\frac{1}{4}=\frac{5}{4}\ hours

1) For Adding :

Total number of hours he practiced on both Monday and Tuesday will be

\frac{7}{10}+\frac{5}{4}\\\\=\frac{14+25}{20}\\\\=\frac{39}{20}\ hours

2) For Subtraction,

Number of hour he practiced more on Tuesday than on Monday will be

\frac{5}{4}-\frac{7}{10}\\\\=\frac{25-14}{20}\\\\=\frac{9}{20}\ hours

What is greater than 40 but less than 20
Paladinen [302]
I've already been complemented twice on my previous answer, but then I discovered that I mis-read the question.  My entire original answer was wrong, and I have to delete it.

I don't believe that any number can satisfy both of those conditions.
I'll say the question has no answer.

Boyd grows only tomatoes and raspberries in his garden. Last year, he grew 140 pounds of tomatoes and 60 pounds of raspberries.
nadya68 [22]

Answer:

29%.

Step-by-step explanation:

We have been given that Boyd grew 140 pounds of tomatoes and 60 pounds of raspberries. This year, the production, by weight, of tomatoes declined by 20 percent, and the production, be weight, of raspberries declined by 50 percent.

First of all, we will find the weight of tomatoes and raspberries using the given information.

Since the production, by weight, of tomatoes declined by 20 percent, so this year production of tomatoes is 80% of 140 pounds.

\frac{80}{100}\times 140=0.80\times 140=112

Since the production, be weight, of raspberries declined by 50 percent, so this year production of raspberries is 50% of 30 pounds.

\frac{50}{100}\times 60=0.50\times 60=30

Total production this year: 112+30=142 pounds.

Now, we will percent decrease formula.

\text{Percent decrease}=\frac{\text{Initial value-Final value}}{\text{Initial value}}\times 100

\text{Percent decrease}=\frac{(140+60)-142}{140+60}\times 100

\text{Percent decrease}=\frac{(200)-142}{200}\times 100

\text{Percent decrease}=\frac{58}{200}\times 100

\text{Percent decrease}=0.29\times 100

\text{Percent decrease}=29

Therefore, the total yield, by weight, of Boyd's garden declined by 29%.
