Answer:

2 2/10

Step-by-step explanation:

first step- make mixed number into improper fraction

solution- 4 3/10=43/10 and 2 1/10=21/10

second step- look at the denominator if the denominator is same let's go to 3 step but if the denominator is different we will solve that

double checkking- 43/10 = 21/10

so the denominator is the same so let's go in third step-now subtract the numerator

solution-43/10 - 21/10 =22/10

so the answer is 22/10( in improper fraction)

and in mixed number is 2 2/10

I hope my answer is correct
