Social Security already answered the first part.

What age does a widow get 100 per cent of her husbands social security benefit?
Social Security benefits at age 62 widow will receive 100 percent of husbands benefits.

Question is: I forgot to ask Social Security, Insteed of 62 what if the age was 60, what percent would it be
Then?

She can only collect when she is 62 and it would not be 100% unless she waits until she is 65 or husband died after age 65. It would be the same if she tried to retire at age 60 she could not collect benefits for herself.

From Social Security: Because you have not remarried, you would be eligible to receive Social Security survivor's benefits as early as age 60 and could later collect your retirement benefits at your full retirement age -- which is 67, not 70. Waiting until age 70 to start collecting your retirement benefits would, however, result in higher retirement benefits than what you would receive at age 67.
