When a matrix is multiplied by a constant, the constant multiplies each of the elements of the matrix.

2\left[\begin{array}{cc}4&0\\-1&5\end{array}\right]=\left[\begin{array}{cc}2\cdot 4&2\cdot 0\\2\cdot(-1)&2\cdot 5\end{array}\right]\\\\=\left[\begin{array}{cc}8&0\\-2&10\end{array}\right]

Ned's frog jumped 38\100 meter.Then his frog jumped 4\10 meter.How far did Ned's frog jump in all?
yanalaym [24]
So first, we need to find a common denominator, make the numbers below the line equal to each other
to do this, we multiply the denominator AND numerator of 4/10 so you can get the equivilent fraction with a denominator of 100
4*10=40
10*10=100
4/10=40/100
now we add the two fractions together and we get 
38/100+40/100= 
78/100 of a meter

Write 0.46 as a fraction in simplest form
butalik [34]
Here's how to convert 0.46 to a fraction...

There is not much that can be done to figure out how to write 0.46 as a fraction, except to literally use what the decimal portion of your number, the .46, means.

Since there are 2 digits in 46, the very last digit is the "100th" decimal place.

So we can just say that .46 is the same as 46/100. The fraction is not reduced to lowest terms. We can reduce this fraction to lowest
terms by dividing both the numerator and denominator by 2.

Why divide by 2? 2 is the Greatest Common Divisor (GCD)
or Greatest Common Factor (GCF) of the numbers 46 and 100.
So, this fraction reduced to lowest terms is 23/50

So your final answer is: 0.46 can be written as the fraction 23/50
