The addition of manganese in steel ___________ the ductile to brittle transition temperature?

The addition of manganese in steel ___________ the ductile to brittle transition temperature? Correct Answer decreases

The addition of manganese decreases the ductile to brittle transition temperature by 5 degrees Celsius with every 0.1% addition of manganese in the steel. The combination of carbon and manganese in steel gives the best result of strength and toughness.

Mr.Rohan while helping the students of Class IV in adding and subtracting fractions observed that several students are not able to complete the addition of two improper fractions. He gave a small test with questions from the addition of proper fractions (one item of addition of two similar fractions, three items from the addition of proper and improper fractions, and four items from the addition of improper fractions). He analyzed the responses of each student and found that nearly 45% of students were not clear in adding proper with improper fractions which were affecting their performance in adding two improper fractions. He, therefore, focused on developing the understanding of improper fractions and their addition with proper fractions after which he proceeded to teach the addition of two improper fractions.
