No. To Use The Same Ratio Se Would Come Up With 4 Cups of Oats and 8 Of Flour. While 2x2 = 4 (Cups Of Oats) 4x2 DOES NOT EQUAL 6 (Cups Of Oats)

No she did not use the same ratio.  She doubled the amount of oats which means she needs to double the amount of flour. If she doubled the amount of flower it would have been 8 cups not 6 cups

Jordan can build a birdhouse in 2 hours. If it takes her sister 3 hours to build a birdhouse, how long will it take them to buil
miskamm [114]
To find the total work of two people at different speeds, we need to find a common speed limit to both.

In this case, Jordan can build a birdhouse in 2 hours so her speed is 1/2 birdhouse per hour.

For the sister, it takes 3 hours to build a birdhouse so her speed is 1/3 birdhouse per hour.

To find what they can do in one hour: \frac{1}{3} + \frac {1}{2} = \frac{2}{6} + \frac{3}{6} = \frac{5}{6}

To find how long does it take to build a birdhouse: \frac{ \frac{5}{6}}{1} = \frac{1}{x}

Set the denominators equal: \frac{\frac{5}{6}x}{x} = \frac{1}{x}

Remove the denominators and solve: \frac{5x}{6} = 1

Once again set the denominators equal: \frac{5x}{6} = \frac{6}{6}

Remove the denominators and solve for x: 5x = 6  \\ \\ x = \frac{6}{5}

6/5 hours is equal to 72 minutes.

5 yrs ago, Nuri was thrice as old as Sonu. 10 yrs later, Nuri will be twice as old Sonu. How old are Nuri n Sonu?​
Papessa [141]

Answer:

Answer will be 50

Step-by-step explanation:

Let us suppose, present age of Nuri be ‘x’ years and present age of Sonu be ‘y’ years.

Now, it is given that five years ago, Nuri was thrice old as Sonu. Hence,

Five years ago,

Nuri’s age = x-5 years

Sonu’s age = y-5 years

And relation between ages can be given as

Nuri’s age = 3×sonu’s age or

x-5 = 3(y-5)

x-5 = 3y-15

x-3y+10 = 0 ………..(i)

Another relation is given in the problem that ten years later, Nuri is twice as old as Sonu.

So, ten years ago,

Nuri’s Age = x+10

Sonu’s Age = y+10

And relation between ages can be written as

x+10 = 2(y+10)

x+10 = 2y+20

x-2y-10 = 0 …………..(ii)

Now we can solve the equation (i) and (ii) to get values of x and ‘y’ or present ages of Nuri and Sonu.

Value of ‘x’ from equation (i) be

x = 3y-10 ……….(iii)

Putting value of ‘x’ from equation (iii) in equation (ii) we get,

3y-10-2y-10 = 0

y = 20

Now, from equation (iii) value of ’x’ can be given as,

x= 3(20)-10

x = 50

Hence, the present ages of Nuri and Sonu are 50 years and 20 years respectively.
