Find the area of the following rectangles. 7/2 mm ×14/5 mm. I can up with 98/10 mm. Please check
5 7/8 km × 18/4 km. I'm stuck please help
huh? It's just like the other one, assuming you know how to change mixed numbers to fractions.
(5 7/8 km)(18/4 km)
= (47/8 km)(9/2 km)
= 423/16 km^2
Please check for me. A rectangular prism has a top face with an area of 20ft2 and a height of 5ft. What is the volume of this rectangular prism. I did 20x5= 100
correct, but I'd reduce the fraction to 49/5
and the area is mm^2, not just mm
correct.
Thanks steve
Is 5 7/8 × 18/4= 423/16
I need help on 7/2mm x 14/5mm i need help on that!
To find the area of a rectangle, you multiply its length by its width. In this case, the length is 7/2 mm and the width is 14/5 mm.
To multiply fractions, you multiply the numerators (top numbers) together to get the numerator of the answer, and then multiply the denominators (bottom numbers) together to get the denominator of the answer.
So, 7/2 mm × 14/5 mm can be calculated as:
(7 × 14) / (2 × 5) = 98/10 mm
Therefore, your answer of 98/10 mm is correct. However, you can simplify the fraction by dividing both the numerator and the denominator by their greatest common divisor, which in this case is 2.
Dividing 98 by 2 gives 49, and dividing 10 by 2 gives 5. So, the simplified fraction is 49/5 mm.
Therefore, the area of the rectangle is 49/5 mm, which is approximately equal to 9.8 mm.
